As reported by the Wall Street Journal: In the future, virtual reality won't require strapping a bulky contraption to your head.
Instead,
imagine stepping into an empty room and then suddenly seeing life-size,
3-D images of people and furniture. Or looking down at a smartwatch and
seeing virtual objects float and bounce above the wrist, like the
holographic Princess Leia beamed by R2-D2 in the movie "Star Wars."
A
key to this future may lay in Carlsbad, Calif., where startup Ostendo
Technologies Inc. has spent the past nine years quietly working on
miniature projectors designed to emit crisp videos and glasses-free 3-D
images for smartphones and giant screens.
Other
companies have shown they can project floating images that appear to be
holograms, but many involve large machines employing a system of
mirrors to direct light with limited viewing angles. For instance, the
lifelike image of the late rapper Tupac Shakur, which graced the
Coachella music festival stage in 2012, was a combination of computer
graphics and video projection that relied on visual effects first
designed in the 19th century.
One chipset, small
enough to fit into a smartphone, is capable of projecting video on a
surface with a 48-inch diagonal. A patchwork of chips, laid together,
can form far larger and more complex images. The first iteration of the
chip, which is scheduled to begin shipping next year, will only project
2-D videos, but the next version, expected to follow soon after will
feature holographic capability, according to Ostendo's chief executive
and founder,
Hussein S. El-Ghoroury.
"Display is the last frontier," said Dr. El-Ghoroury, who in 1998 sold CommQuest Technologies, a mobile chipset company, to
International Business Machines Corp.
IBM -0.41%
for about $250 million in cash and stock. "Over the years,
processing power has improved and networks have more bandwidth, but what
is missing is comparable advancement in display."
The
race to disrupt the screen is intensifying as both upstarts and
technology giants try to find new ways to bring content to life.
Facebook CEO
Mark Zuckerberg
was, in part, convinced of the value of virtual reality after he
accidentally tried to set down a real world object on a virtual table
while testing the Oculus Rift, forgetting for a moment that the table
didn't exist in the real world, according to a person with knowledge of
the matter.
Ostendo, tucked away in
Southern California, is little-known but has raised $90 million from
venture-capital firms and
Peter Thiel,
Facebook's first outside investor, and has secured some $38
million in government research and development contracts. A large bulk
of that has come from the Defense Advanced Research Projects Agency, or
Darpa, the government's futurist agency that worked on the predecessor
to the Internet and self-driving cars.
That
capital has given Dr. El-Ghoroury, an immigrant from Egypt, the luxury
to work for nearly a decade undisturbed. Ostendo now employs about 115
people, including scientists suited in scrubs and goggles who handle
fragile nanotechnology equipment at a high-tech semiconductor lab.
The long effort has yielded the
Ostendo Quantum Photonic Imager, an appropriately sci-fi-sounding name,
which fuses an image processor with a wafer containing micro
light-emitting diodes, or LEDs, alongside software that helps the unit
properly render images.
During a recent
test reviewed by The Wall Street Journal, Ostendo showed a working
prototype: a set of six chips laid together that beamed a 3-D image of
green dice spinning in the air. The image and motion appeared
consistent, irrespective of the position of the viewer.
According
to Ramesh Raskar, an associate professor at the Massachusetts Institute
of Technology, who is working on 3-D displays for MIT's Media Lab,
Ostendo's advantage and the key to its 3-D capability is its resolution.
The Retina display on Apple Inc.'s iPhone, for example, has about 300 dots per inch, Ostendo's chips are at about 5,000 dots per inch.
Ostendo,
which says it has several opportunities with major handset
manufacturers, expects the first 2-D projector unit to be in the hands
of consumers before the summer of 2015. With a lens attached, it will be
less than 0.5 cubic centimeters, roughly the size of the camera in the iPhone.
It also expects to begin manufacturing the second version of the chip,
with 3-D capability, in the second half of 2015. The cost to the
consumer should be about $30 a chip, Ostendo estimates.
Dr. El-Ghoroury said the company still needs
to improve the 3-D product and is aiming to make the pixels even
smaller to achieve higher resolution.
Ultimately,
the larger vision is to have Ostendo's chips everywhere electronic
displays are needed, whether it is a glasses-free 3-D television screen,
a smartwatch, or tables that can project hologram-like images.
So
what happens in a world where 3-D and virtual reality is everywhere?
Dr. El-Ghoroury predicts people's relationship with technology will
change and breed a wave of business opportunities, on scale with the
introduction of the iPhone.
"Imagine if
everything coming back to you was in 3-D—all of your shopping, all of
your gaming, every way you retrieve data," he said.
After
a tornado, streets usually are covered in debris. Street signs may be
missing. It’s also sometimes difficult to tell from the debris where
homes once stood. When emergency responders arrive, they spend a lot of
time hoping they have picked a good spot to dig.
